United States Patent O M 3,049,836 RFING REPAR PATCH Eugene Weissman,Libertytowu, Md. Filed heb. 27, 1959, ser. No. 796,104 1 Claim. (Cl.50-243) This invention relates in general to home repair devices, andmore specifically to an improved rooting repair patch.

A majority of the homes in this country are provided with compositionroofs. While such roofs are extremely effective, they are subject todamage by nails, tears and blisters. Even though the damage to a roofmay be Small, during a rain storm water will leak through such a smalldamaged place -and into the building causing a very great amount ofdamage. On the other hand, if a simple repair were effective, `thisdamage could be eliminated. However, due to the construction of thecornposition roof, it is normally necessary to replace individualshingles and since such shingles are interlocked, it is practicallyimpossible for the average person to do this. Thus it is necessary thata roofer be called in at a relatively great expense to the house ownerand in many instances with a delay which will prove costly duringinclement weather.

It is therefore the primary object of this invention to provide a roofrepair patch which is of such a nature whereby it is only necessary forthe homeowner or other person attempting the repairs to locate thedamaged area of the composition roof, place the repair patch over thedamaged area and step upon the repair patch at which time the repairpatch will be effectively applied.

Another object of this invention is to provide an improved repair patchfor use in construction with composition roofs, the repair patchincluding a shell which is of a pan-like construction and which hasdisposed in the lower part thereof a suitable mastic which is covered bya membrane, the membrane having openings therethrough whereby when theshell is disposed in an inverted position over a damaged area andpressure is applied to the shell by stepping thereon, the mastic will beforced through the membrane and into engagement with the roof so as toadhere the membrane to the roof and thus seal the damaged area.

Still another object of this invention is to provide a repair patch forcomposition roofs and the like, the repair patch being of an extremelysimple construction and readily applicable, said repair patch beingformed of a pan-like shell which is formed of a thin metal material,such as a foil, and having disposed in the lower portion thereof amastic which is overlaid by a membrane preferably in the form of roofingpaper, the mebrane having openings therethrough through which the masticmay flow so that the repair patch may vbe applied merely by positioningover the dam-aged area and applying a relatively great pressure thereonto deform the shell and cause the mastic to ow through the openings inthe membranes so that the mastic will engage the roo-f and seal themembrane to the roof surrounding the damaged area.

A further object of this invention is to provide a repair patch forcomposition roofs and the like which may be applied during inclementweather, the repair patch including a lightweight shell which isdeformable and which is of the pan-type, the shell having disposed inthe lower portion thereof a mastic which is overlaid by a membrane, suchas roofing paper, and there being disposed in the upper part of theshell the water resistant adhesive within a frangible container so thatwhen the patch is applied by pressure, the shell will deform and thefr-angible container broken so that the adhesive will spread over thedamaged area and adhere to the roof notwithstanding the 3,049,836Patented Aug. 21, 1962 ICC fact that the roof is wet and thus aid in thesealing of the damaged area by the mastic and membrane.

These together with other objects and advantages which will becomesubsequently apparent reside in the details of construction andoperation as more fully hereinafter described and claimed, referencebeing had to the laccompanying drawings forming a part hereof, whereinlike numerals refer to like parts throughout, and in which:

lFIGURE, 1 is a bottom perspective view of one form 4of repair patch,showing the general outline thereof;

FIGURE 2 is an enlarged plan view of the repair patch of FIGURE 1 andshows the arrangement of the openings in the membrane thereof;

FIGURE 3 is an enlarged longitudinal sectional view taken substantiallyupon the plane indicated by the section line 3 3 of FIGURE 2 and showsthe specific details of construction of the repair patch;

FIGURE 4 is a transverse sectional View taken through the repair patchsubstantially upon the plane indicated by the section line 4 4 of FIGURE3 and shows further the details of the repair patch;

FIGURE 5 is `a bottom perspective view of a second form of repair patch;

FIGURE 6 is an enlarged longitudinal sectional view taken substantiallyupon the plane indicated by the section line 6 6 of FIGURE 5 and showsthe specific details of the construction of the repair patch of FIGURE5; and

FIGURE 7 is a transverse sectional view taken sub stantially upon theplane indicated by the section line 7 7 of FIGURE 6 and shows Kfurtherthe details of the repair patch.

Referring now to the drawings in detail, it will be seen that there isillustrated in FIGURES l, 2, 3 and 4 a rst form of roofing repair patchwhich is referred to in general by the reference numeral 10. The roongrepair patch 10 includes a shallow pan-like shell 12 which has a bottomwall 14, upstanding end walls 16 and upst-anding side walls 1S. The endwalls 16 terminate at the upper edges thereof in inturned flanges 20 andthe side walls 18 terminate at the upper edges thereof in similarinturned flanges 22. Disposed in the lower part of the shell 12 .andoverlying the bottom 14 thereof is a suitable mastic such as thatnormally used in the repair of roofs. The mastic is referred to by thereference numeral 24. Overlying the mastic 24 is a membrane 26 which ispreferably in the form of roofing paper. The membrane 26 has formedtherein a plurality of elongated openings 28 which are best illustratedin FIGURE 2. The membrane 26 is held in place by the flanges 20 and 22of the shell 12.

At this time it is pointed out that the shell 12 may be formed of anysuitable deformable material so that when pressure is applied thereto itwill atten out. It is preferred that the shell 12 be formed of a thinaluminum foil which will have suicient rigidity to support the repairpatch prior to the positioning thereof and of a sufficient thickness toprotect the elements of the repair patch once it has been applied.However, undoubtedly other materials will be developed which will suiceor replace the aluminum foil as a `desired shell forming material.

In the use of the repair patch 10, once the damaged area has lbeenlocated, the repair patch 10 is placed over the damaged area with thepan-like shell 12 in an inverted position. That is, the bottom 14 of theIshell 12 is disposed uppermost. Then pressure is applied to the shell,preferably by stepping on the shell 12 so that the shell 12 is deformed.Inasmuch as the mebrane 26 will initially engage the damaged area of theroof and since the mastic 24 will be forced through the openings 28 inthe membrane 26, it will be readily apparent that although the mastic 24is initially disposed uppermost, the mastic 24 will flow beneath themembrane 26 and provide the desired seal between the roof and themembrane 26. Once, the repair patch has been applied, it will beprotected `by the shell 12. Furthermore, 'as is well known when heat isyapplied to the roof by the sun, the mastic 24 will have a tendency tosoften and completely ow beneath the membrane 26 to provide a permanentseal.

Referring now to FIGURES 5, 6 and 7, it will be seen that there isillustrated a second form of repair patch which is referred to ingeneral by the reference numeral 30. The repair patch 30 includes ashallow pan-like shell which is referred to in general lby the referencenumeral 32. The shell 32 has a bottom wall 34, and upstanding end walls36 and side walls 38. Disposed in the lower part of the shell 12 andoverlying the bottom Wall 34 thereof is a suitable mastic 40, such asthe mastic 24. Overlying the mastic 40 is a membrane which is formed ofa roofing paper, the mebrane being referred to by the reference numeral42. The membrane 42 is provided with a plurality of openings 44 topermit the ow of the mastic 40 through the membrane 42 when the rootingrepair patch 32 is applied.

It will be readily apparent that the shell 32 is deeper than the shell12 and that the mebrane 42 is disposed below the upper edge of the shell32. Thus space is left in the upper part of the shell 32 for thereception of a at container 46. The flat container 46 is formed of afrangible material, such as a thin iiexible plastic. Disposed Within thecontainer 46 is a conventional household adhesive of the type which maybe applied over a wet surface and the adhesive will adhere to such Wetsurface. The adhesive 48 is not a critical part of the invention and maybe one of the numerous household adhesives which will function in themanner outlined.

When it is desired to apply the repair patch 30, it is merely necessaryto locate the damaged area of the roof. Then although the roof may beWet due to inclement weather, it is merely necessary to place the repairpatch 30 in its invented position, that is with the bottom of the shell32 disposed uppermost, in overlying relation to the xdamaged area. Therepair patch 30 is then applied by applying pressure to the shell 32.This pressure is most easily applied by stepping on the bottom 34 of theshell 32. As pressure is applied to the shell 32, the contaner 46 willbe rst ruptured so that the ladhesive 48 will flow over the damagedarea. Continued downward movement of the bottom 34 of the shell 32 willresult in the engagement of the membrane 42 with the roof surface inoverlying relation to the adhesive 48. Further, the pressure applied onthe mastic 40 by the bottom wall 34 and shell 32 will result in the iiowof the mastic 40 in limited quantities through the openings 44 in themembrane 42. Thus, the membrane 42 will be secured to the roof both bythe adhesive 48 and by the mastic 40. 55

Further, inasmuch as the mastic 40 will have a tendency to ow duringWarm weather through the elevation of the temperature of the roof fromthe sun rays, the mastic 40 will continue to tiow with respect to themembrane 42 and thus provide a more effective seal. At the same time,the shell 32 will protect the components of the repair patch.

From the foregoing, it will be readily apparent that there has beendevised an extremely simple repair patch which is of such a constructionwhereby it may be effectively applied toa roof to seal a damaged area.Further, the repair patch is of such a nature whereby it may be storedin quantities or may be distributed in the local hardware stores so thatat such time as the roof of a building is slightly damaged, it is merelynecessary for the houseowner or other person to locate the ldamagedarea, acquire a repair patch of the desired size and then place therepair patch over the damaged area and applying pressure -tiherctomerely by stepping on it. Thus, the average small roof repairnecessitated by the tearing of composition shingles may be accomplishedby an unskilled person.

The foregoing is considered as illustrative only of the principles ofthe invention. Further, since numerous modiiications and changes willreadily occur to those skilled in the art, it is not desired to limitthe invention to the exact construction and operation shown anddescribed, and accordingly all suitable modiiications and equivalentsmay be resorted to, falling within the scope of the invention asclaimed.

What is claimed as new is as follows:

A rooting repair patch comprising a shallow inverted pan-like shell, amastic composition in the upper portion of said shell, a membrane in theshell underlying the mastic composition, a frangible container in theshell underlying the membrane, and -a waterproof adhesive in thecontainer, said shell being exible and crushable under foot pressure forrupturing the container and freeing the adhesive -for securing the patchto a roof, said membrane having preformed, unobstructed openings thereinof such dimensions as to normally retain the mastic composition butthrough which said mastic composition will extend in response topressure on the shell for further securing the patch to the roof.
